The power plant Shin-Nagoya ( Jap. 新名古屋火力発電所 , Shin-Nagoya karyoku hatsudensho ) is a gas power plant in Japan , which on the east side of the Ise Bay in the city of Nagoya ( Aichi Prefecture ) on a Meeresaufschüttung located. With an installed capacity of 3,058 MW , it ranks fifth among the most powerful power plants operated by electricity supplier Chūbu Denryoku .
Power plant units
The power plant consists of a total of ten units with different capacities that went into operation in 1998 and 2008. The following table gives an overview:
| block | designation | Max. Power (MW) | Start of operation | turbine | generator | Steam boiler |
|---|---|---|---|---|---|---|
| 1 | 7-1 | 243 | 08.1998 | General Electric (GE) | Toshiba | IHI |
| 2 | 7-2 | 243 | 10.1998 | GE | Toshiba | IHI |
| 3 | 7-3 | 243 | 11.1998 | GE | Toshiba | IHI |
| 4th | 7-4 | 243 | 11.1998 | GE / Toshiba | Toshiba | Toshiba |
| 5 | 7-5 | 243 | 12.1998 | GE / Toshiba | Toshiba | Toshiba |
| 6th | 7-6 | 243 | 12.1998 | GE / Toshiba | Toshiba | Toshiba |
| 7th | 8-1 | 400 | 10/01/2008 | MHI | Melco | MHI |
| 8th | 8-2 | 400 | 07/01/2008 | MHI | Melco | MHI |
| 9 | 8-3 | 400 | 06/01/2008 | MHI | Melco | MHI |
| 10 | 8-4 | 400 | 04/01/2008 | MHI | Melco | MHI |
The blocks are referred to by Chubu as 7-1 to 7-6 and 8-1 to 8-4. The previously existing six blocks have already been taken out of service.
The estimated costs for Units 1 to 6 are US $ 1.2 billion . The gas turbines in these blocks are of the type MS7001FA from GE, in which the gas turbine drives the generator with the steam turbine on a common shaft ( single-shaft CCGT ).
Construction of units 7 to 10 began in July 2005. According to Chubu, the thermal efficiency of these blocks of 58% represents the current world record. Each block consists of a gas turbine of the type M501G1 and a steam turbine of the type SRT-45, which were supplied by MHI .
fuel
All units in the power plant use LNG as fuel. There are other Chubu power plants ( Chita , Chita Daini , Kawagoe and Yokkaichi ) that use LNG as fuel around Ise Bay . The Shin-Nagoya and Chita power plants are connected by an underground tunnel through which gas pipes run.
Others
A pilot plant for flue gas desulphurization and denitrification is located on the site , which is based on a process developed by the Japan Atomic Energy Research Institute and Chubu, in which sulfur oxides (SO x ) and nitrogen oxides (NO x ) are converted into artificial fertilizers via the intermediate stages sulfuric acid and nitric acid .
The electricity generated is carried over a 275 kV line to the nearby substation in Tōkai , which is designed as a gas-insulated pipe conductor with an outside diameter of 46 cm. The line is located in the upper half of a tunnel with a diameter of 5.6 m, which runs at a depth of 30 m underground. There are lines for LNG in the lower half of the tunnel.
